About this watch

The Omega Speedmaster Professional Moonwatch 311.30.42.30.01.005 is a horological masterpiece that combines rich history, timeless design, and precise functionality. At its heart lies the Omega caliber 1861, a hand-wound movement that echoes the legacy of the original Moonwatch. The 42mm stainless steel case boasts a perfect balance between presence and wearability, while the matte black dial with stick and dot indexes exudes sophistication and sportiness. A plexiglass cover adds vintage charm, although it may scratch more easily than sapphire. With a water resistance of 50 meters, this watch is suitable for everyday wear but not recommended for swimming or diving. The chronograph feature allows users to time events with precision, making it perfect for sports enthusiasts and those who appreciate the technical specifications of timekeeping. Wearing the Speedmaster Professional Moonwatch is an experience in itself, with a solid bracelet that fits snugly and offers flexibility throughout the day. Whether formal or casual, this watch sits comfortably on most wrists, drawing compliments like moths to a flame.
